Thread: Interlock Sealing

Does anyone have any experience pulling weeds, re-sanding interlock and sealing it. A customer is asking me to do this and I have no idea what to charge for such a job. Seems like a simple job, but am I missing anything here?

I wouldn't use sand. I would pressure wash out all the sand from the joints, let it dry than redo the joints with polymeric sand. This will harden similar to concrete (no it isn't concrete) and will prevent weed growth!
